12.1 EDK, PLBv46 RC/EP Bridge for PCI Express (v4.04a) - Is the EDK PCIe core Gen2 compliant?


Does the core support Gen2 speed for Virtex-6 devices?


No, the EDK PLBv46_PCIe core is limited to 2.5Gb/s.
The Virtex-6 PCIe core used in the design is PCIe v2.0 compliant. The bridge design uses this core for the Virtex-6 FPGA implementation and identifies itself on the PCIe bus as v2.0 compliant. Both 5Gb/s and 2.5 Gb/s speeds are supported in PCIe v2.0. The bridge design is limited to 2.5 Gb/s. The document for v4.04 of the plbv46_pcie has a note added to indicate this.
